Patent number: 11766177Abstract: A dental probe for determining the vitality of a tooth, comprising a light emitter and a light receiver, wherein the light emitter emits light from an emitter surface adapted to be positioned on a hard dental surface of a tooth, wherein the light receiver collects light incident on a receiver surface adapted to be positioned on a hard dental surface of the tooth so that the optical path of the light emitted from the light emitter passes at least through a portion of the pulp chamber of the tooth. The light receiver includes a light shielding spacer member adjacent to the optical path for establishing and maintaining a distance of at least 50 ?m between the gum line and the optical path at the receiver surface.Type: GrantFiled: June 3, 2021Date of Patent: September 26, 2023Assignee: DENTSPLY SIRONA INC.Inventors: Thomas Ertl, Naim Karazivan, Alexander Savic

Patent number: 10238476Abstract: A method of attaching a dental article to the surface of a tooth includes providing the dental article and applying a coating including upconversion phosphors to a surface of the dental article. The method also includes applying a dental cement composition to the surface of the tooth and placing the dental article on the surface of the tooth such that the coating is adjacent the dental cement composition. The dental cement composition includes a polymerizable resin and a photoinitiator and is substantially free of upconversion phosphors. The method further includes irradiating the coating with a radiation source that emits radiation at a pre-determined fixed wavelength that causes the upconversion phosphors to emit radiation at an activation wavelength of the dental cement composition photoinitiator such that the dental cement composition cures in a region adjacent the coating and removing remaining uncured dental cement composition outside the dental article from the tooth.Type: GrantFiled: May 2, 2017Date of Patent: March 26, 2019Assignee: DENTSPLY SIRONA INC.Inventors: Naim Karazivan, Hui Lu, Thomas Ertl
